What I'm talking about is to set the transparency level of a PNG from within PTP!In krpano it's a single alpha parameter and it doesn't occur to me why that isn't used in PTP as well, as it allows the designer to easily tweak the appearance of a tour.

PNGs with predefined alpha so far worked for me, but of course I haven't tested all possible options and combinations. I leave this to all the other people who, like me, happily paid for an unfinished software *evilgrin*.

That has never been offered in PT/PTP. You could/should propose it as a feature request.
